Winter freeze shows value of offshore wind
Utility-scale wind farms helped maintain electricity supply and moderate prices amid a bitter cold snap in the northeast US.

USA: Bone-chilling temperatures and Arctic winds swept across the northeastern US in recent weeks, putting pressure on electricity systems and pushing up power costs as households increased heating. Early data now shows that offshore wind farms played a key role in keeping electricity flowing during the extreme weather.
The region’s two operating utility-scale projects – South Fork Wind and Vineyard Wind – performed strongly, with capacity factors comparable to efficient gas plants and outperforming coal-fired facilities.
The 132-MW South Fork Wind farm supplied Long Island with power at a 52 % capacity factor in January, similar to the region’s top gas generators. The 12-turbine project, the first US utility-scale offshore wind farm, now serves roughly 70,000 homes.
Vineyard Wind, nearly complete and capable of 600 MW, achieved a 75 % capacity factor during the same period. Once fully operational, it will provide competitively priced electricity to New England, reducing the need for expensive oil-fired plants during winter peaks.
Officials highlighted how offshore wind’s contribution helped ease grid stress, reduce reliance on high-cost fossil fuels, and support electricity reliability. Data centre demand, electrified homes, and vehicles all benefit from the added capacity.
Looking ahead, additional projects like Sunrise Wind and Empire Wind are expected to add 1.7 GW of capacity, helping the Northeast meet growing energy needs and maintain grid stability in future cold-weather events.
